What's the closest web-safe font to Roboto?
I need to know this in order to provide a decent alternative to Roboto for my apps.
UPDATE: reading the answers, it's clear that the concept of web safe needs to be clarify. Actually I'm referring to the webdev concept of web safe: http://www.w3schools.com/csSref/css_websafe_fonts.asp
which includes the following:
The "web-safe" is a little arcaic concept.
It is more likely that your site dissapear before google stop supporting the fonts it has listed. So any alternative to other "google fonts" has no sense.
If you want to complement your style use:
font-family: "Roboto", Arial, Helvetica, sans-serif;
